I'm having this problem since an year or so (everything was normal before, so it is not the games, not the control panel settings and not the drivers newer/older).

I saw a topic here about the same problem (it was from 2008, and it was with radeon 4870 x2)
where 2 people were having it, and there was no solution replied.

I have seen many thread with this problem on the web, but again with no solution found.

So, I am with Windows 7 32-bit, Geforce 8800GT. The problem consists in poor draw distance and a texture "change" in 95% of the games. It is not only for objects on the background, but in closer object, where the texture "changes" (or pops in, dunno how to describe it) when i make a step forward, and changes again when i go back

this is almost undoubtedly the games themselves, just model level of detail at work trying to save you performance.

it'll swap to a higher quality model when it figures you're close enough to actually notice the detail. this isn't your system doing something terrible, it's just an incredibly common optimization at work.

Here are some other commands, if ya want I can tell you what each one does.
e_lod_ratio=6
e_lod_min=0
e_lods=1
e_view_dist_ratio = 100
e_view_dist_ratio_detail=100
e_view_dist_ratio_vegetation=100 This one here can get rid of popups.
e_view_dist_custom_ratio=200
e_vegetation_sprites_distance_custom_ratio_min=1
e_vegetation_sprites_distance_ratio=1.5
e_detail_materials_view_dist_xy=4096
e_detail_materials_view_dist_z=256

I know about editing the cvars in Crysis, but this is bot only in Crysis, and this "wheel change" wasn't happening the first time I played Crysis. I was just giving an example what is happening in almost all games

I created an autoexe.cfg file in the Config folder of Crysis, added the command but nothing happened.

I just renamed it to autoexec.cfg and the tyre isn't "changing", but the npcs are still bugged
Can i do the same file for all the other games?

But this means that i have a general problem with the LOD settings and i have to manually adjust them for each game. I tried with Rivatuner but it makes no change.

And I know that this is not normal behavior . I know how things were before this started to happen.

No, it most likely just means that you didn't notice it the first time you played through it and now that you noticed it for 1 game you start noticing it in all the other games. I'm almost 100% positive this is just normal Level of Detail; it's the Game-engine doing this, not some fault in your hardware.

The texture change of the sandbags in COD 2,4,6 is so obvious that it is just impossible i didn't noticed it before. I am 100% sure that wasn't happening. I know what normal LOD and draw distance is and that this is not normal.

This guy has bugged LOD (more obvious when you look at the trees). If you that this is normal behaviour, i can say that i also played it some days ago, and it wasn't like that.

It was one of the few games that are absolutely normal (which is strange). Also i have found different topics on the web with ppl that have the same problem (there also was example with COD and the problem was like mine).

So the next time I manage to reinstall Windows, I will put back XP and see if that changes something (there is chance it wouldn't, because there were people trying this with no help), because I first noticed this soon after i put Win7 for the first time.

I posted this because i wanted to see it anyone here has the same problem (like an older thread about a guy with the same problem, there was another with the same thing happening).

Anyway, thanks to all who responded.

I'm facing the exact same problem recently in everygame. I have an ASUS 4870 1Gb and there's popping in BC2, STALKER's, Crysis, a little in CoH ... the Ungine Heaven tests... And It's driving me crazy. Maybe has to do something with DirectX10/11?

Sure I notice too. I notice it when I move around and face some objects (grass, boxes, even highly textured zones). When I walk near this objects or textures they suddenly appear in front of me, a drastic transition between not beeing seen and beeing seen (objects) or low quality LOD and high quality detailed textures. I don't know how to explain better. In some games it's a noticeable effect (BC2, STALKER, Crysis, GTA IV...) and in others the effect is barely noticeable (CoH, Ungine tests, Futuremark tests, Borderlands, CoD...).

As gnb said, it's not the resolution. I have already tested this and lowering the res doesn't help. At firs I thought that was something with the memory frecuency, but I tried to lower it from its defaults and that doesn't help neither.

I also thought that was Windows 7, but I reinstalled Windows XP x64 and it was happening to in native DX9 mode.

If you can move back and forth and make the transition happen yourself, then it is the game, plain and simple. There is nothing else to it.

You're just seeing model LOD. The graphics API doesn't do this, your hardware doesn't do this. It's up to the game engine to handle... which also makes it easy to take pictures of since in COD4 it's just a console command. You won't find a solution outside of turning detail settings up in game.
